Clock with calendar display

The invention relates to a clock with a calendar display, which is to be understood as meaning that this clock has day and / or data displays. In conventional watches of this type, it is known to provide a rotatable ring body on which the data numbers 1 to 31 are printed, these data numbers then appear in a window on the dial. The ring body, which can be set in rotation, is driven by an intermediate drive device through the hour hand of the clock and a device is created that makes a next number visible in the window of the dial after every 2M hours.

Now, since not all months of 31 days, it is necessary at the end of the month, which have less than 31 days to twist this ring body so

the number 1 becomes visible in the window on the first day of the following month, such an adjustment of the ring body is usually made by hand namely by means of the adjusting crown of the clock, which for this purpose is pulled "out of the clock case" and turned further must be grounded. Depending on the structural design of the various clocks that are on the market, the temporal loss varies, i.e. after correcting the date it is necessary to bring the clock back to the correct time of day.

In connection with the above-mentioned facts, it is present as a first task To view the invention, a drive device for the adjustment of the data-carrying ring body is available which not only rotates the ring body by one digit after every 24 hours, but Manual rotation is permitted, even if the exact time of day is maintained, if months are more unequal Consecutive number of days. To solve this problem, the watch has a manually operated adjusting device on, which can be brought into operative connection with the setting crown, with a correction of the data-carrying ring body ^ is made possible without "this setting crown from the watch case needs to be pulled out, or the pointer must be moved in the axial direction. this

but means that to twist the ring body up to correct date number the Stelllcrone "in their> normal "Inward position can be left and only needs to be turned clockwise until the correct date appears in the window of the dial.

A clock that correctly displays the day of the month does not necessarily have to display the day of the week. It is now known that clocks in addition to a day display also have a weekday display, lst which hold ₉ that a simple coupling not these two types can be selected. It is; Yes, in this context it is known that the individual days of a month do not invariably coincide with the individual days of the week, in particular that the relative relationship constantly changes over the course of the months and years. For example, Bo, the first of January 1967 fell on a Sunday, while the first of February 1967 fell on a Wednesday. It is therefore necessary that the weekday display can be adjusted relative to the day display, so that it is ensured that the first day of each month corresponds to the corresponding weekday.

In connection with the facts outlined above, there is inevitably a second task According to the present invention, which can be seen therein, an independent adjustment of the day display

and to enable the weekday display, whereby the connection to the first task indicated above is to be seen in the fact that this adjustment option is carried out without disturbing the respective time of day. The present invention to be provided to the end part of a clock device so shall at the expiration of each 2h hours both day display the weekday display .how continue to move gradually.

The detailed components of a clock for solving the indicated tasks are given below Exemplary embodiments shown in the drawing are described in more detail. It shows:

Furthermore, according to the invention, a manually operable adjusting device is provided which is independent works on the action of the trigger and enables only adjust the data ring by turning the setting crown in its "upwards" position.

The device according to the invention is located in the interior of the watch case 10, which is penetrated laterally by the adjusting shaft 11 with adjusting crown 12, which enables the time to be adjusted. On the end of this adjusting shaft 11, a coupling wheel 13 is placed in a square section, which is freely displaceable in the axial direction. In a known manner, this clutch ^{wheel 13 can now be brought into operative connection by means of a clutch lever I 1} I with an adjusting wheel, not shown, when the adjusting crown 12 and thus also the adjusting shaft 11 is pulled "out of the housing", since the aforementioned adjusting wheel with the also meshes with the minute wheel, which is not shown, the exact time can therefore then be set when the setting crown 12 is rotated. The hour wheel is denoted by the reference number 15 and this hour wheel now meshes with the trigger provided according to the invention for adjusting the data ring body; this trigger will be discussed in more detail below.

and its 17 is provided with 31 _s Inner circumference same Abstandjvoneinander having teeth. Each tooth 17 has a number on the ring body 16 arranged between the dial and the base plate, PP, so a total of 31 numbers are provided corresponding to the day number of the longest months.

From Figure 9 it can be seen that the dial D with a window W is provided, through which the corresponding day of the month and the day of the week for Display can be brought.

For the further turning of the data ring 16, which can be actuated by hand, a collar 18 is now initially arranged on the actuating shaft II, the projection 19 of which is operatively connected to the teeth 17 of the adjusting ring 16 so that the connection? set of the adjusting ring 16 to enable. The collar 18 is also provided with a ratchet wheel l8 a, the teeth 18 b of which mesh with the teeth of the clutch wheel 13 only in the "inward" position of the actuating shaft Uralt. The waistband * 18 is fixed to the actuating shaft 11 such that it is rotated only during rotation of the actuating shaft in the clockwise ,, it 1st simultaneously made provision that the projection 19 niüt with the teeth 17 of the data ring 16in, operative connection comes _s when this Data ring is automatically rotated further.

clockwise, then, as already indicated, the projection 19 comes into engagement with a tooth 17 of the data ring 16 with each full revolution of the actuating shaft; ! Lock 20 is provided, which is in operative connection with the teeth of the data ring due to the bias of a spring 21. When the actuating shaft is pulled out, the ratchet wheel 18 disengages from the clutch wheel 13, because the clutch ^{lever I 1} J then ensures that the clutch wheel 13 comes into engagement with the actuating wheel (not shown). This describes that with the precise setting of the tent it is not possible to turn the data ring.

The reference number .22 designates a leaf spring which, through its operative connection with the projection 19 of the federal government 18 a free turning of the setting crown 12 and thus also a. random further turning of the data ring 16 prevents, so the projection 19 must first overcome the bias of this leaf spring 22 before it engages can be brought with a tooth of the data ring, so that only then allows further turning of the same will. Purely the rotation of the adjusting shaft 11 must therefore be a certain initial force exerted. This initial force also ensures at the same time that an unintentional "overturning" of the Stellweiß is prevented.

meshing gear 23, which rotates every 2 hours by a full turn. Arranged on this gear wheel 23 is a finger 2 ^{1 which} rotates with it about a common axis and which rotates in the recess 25 of a switching arm 26. As can now be seen in particular from FIGS. 2 to 6, the recess 25 has an essentially semicircular cross section, the semicircular wall 25a of which is never touched by the front end of the switching finger 24 during its rotation. The somewhat convex wall 25 b and the nose 25 c are touched, and a notch 25 d is formed between 25 b and 25 c.

As can be seen from Figure 1, is at the free end of the Switching arm 26 in a slot 27 of the base plate PP guided stop pin 31 is provided, which allows free rotation of the switching arm 26 with simultaneous back and forth Moving forward in the slot 27 guaranteed.

The touch of buffer pin and flake area 32 is made possible by the fact that a The nose 33 of the switching arm 26 is in contact with a switching spring 30, the arrangement as a whole is such that when the switching finger 24 is rotated, the switching arm 26 changes its position.

The reference numeral 3 ¹ I also denotes a circular disk which is fixed within the teeth 47 of the data length 16 via screws 35, 36 on the base plate PP the shaft 38 of the hour wheel 15 engages through it, so this shaft 38 carries the hour hand of the clock. The central opening 37 is surrounded by a raised hub part 39 which is provided with a recess ¹ JO for receiving the components of the weekday ring 41 rotating around it. This weekday ring 4l is provided with an inner toothing 42 having 1H teeth, so the weekday sequence appears twice on the surface of the oil ring. This ring 4l is set in rotation by a switch pin 41 fixed opposite the switch arm 26; this switch pin sits near the recess 25d and passes through an opening 44 of the bridge 34, it is in engagement with the teeth of the

Wheel ² Jl, with the reference number 45 is under the action of a pretensioned spring ¹ IS lock referred to, which is in engagement with the teeth of the ring kl.

As will be described in more detail, shortly before midnight, the rotating shift finger 2k assumes a position such that the holding arm 26, which is pretensioned by the spring 30, is held in a so-called blocking position. Shortly thereafter, the switching arm 26 is "relieved" by the switching finger 2k , as a result of which the projection 28 is brought into engagement with a tooth 17 of the data ring 16, so that it is rotated "by a day" -WeItB? At the same time, the switching pin ■ k ~ $ comes into operative connection with a tooth of the ring kl _s so that this ring is also rotated further. Then the switching arm 26, which then comes into contact with the Pr.ell pin 29 again, assumes its starting position.

in the following it will now be described with reference to FIGS . 2 to 6 what significance the individual positions of the switching finger 2'J have with regard to the further rotation of the data ring i6. Tn FIG. 2, a position of the shift finger 2k is now first shown, which it assumes shortly before the “relief” of the shift arm 26, that is to say at a point in time which is approximately 11:59 p.m. In this position, the tip of the switching finger is opposite the rabbit 25 c of the recess 25 .'d. On his Wefj to zn this rabbit 25e the switch finger 2.k has

to overcome the biasing force of the spring 30, thereby shifting the switch arm 26 into the so-called "locking position" in which the stop pin 31 is located near the lower end of the slot 27 in the base plate. In this blocking position, the switching arm is furthest away from the buffer pin 29 and the nose 28 is between the teeth 17 A and 17 B of the data ring 16, where it assumes a position that is immediately in front of the tooth 17 A. If the switch finger 2k continues to rotate counterclockwise, then its front tip disengages from the nose 25 C, so that the switch arm 26 suddenly moves forward under the action of the spring 30, the switch arm is "relieved" and the stop pin 31 becomes pushed forward in the slot 27. The switching arm 26 comes into contact with the bounce pin 29. However, the relief of the switching arm 26 also comes into contact with its nose 28, the tooth 17 B of the data ring 16, so that it is rotated as a result.

If the switching arm 26 is "relieved" or "triggered", then

of the "switching arm 26 to form, but also at the same time to prevent rotation of the switching arm when this over its projection 28 with a subsequent tooth 17 A of the data ring should come into contact. In addition the contact pin 29 also serves the purpose of enabling the sliding and rotating forces of the switching arm 26 to work together, if this with, its moclc area 32 intestines the bounce pin 29 rests when the shift finger 2 * 1, as will be described with reference to the figure, in contact with the convex wall 25 b of the .Switch arm 26 is.

In Figure 3, the "relieved" position of the trigger device is shown. It is shown that the cam surface is present in this position 32 at the Prelüsbift 29 which Anächlagstift 31 is then in the upper area .of the slot 27 and the lug 25 is located on the straight surface of the c Sehaltfingers 2 ¹ J to. The position of the holding finger and the switching arm shown in the figure is that at midnight.

If the tip of the switching finger 2h now comes into contact with the convex wall · 25b of the recess in the switching arm 26, the projection 28 of the switching arm 26 is thereby formed. lifted out of the engagement area of the teeth of the data ring and control takes place via the cam surface 32, which is in contact with the buffer pin 29. The spring 30 fulfills the task of the required abutment and the stop pin 31 is displaced in the slot 27 while the switching arm 26 rotates at the same time. This “simultaneity” of the displacement movement and the rotary movement is therefore indirectly supported by the bounce pin 29, as already explained above. If the tip of the switching finger 2 ¹ I then comes into the area of the recess 25 d at around 7 p.m. (see Figure 5), it then also hits the nose 25 c at the same time, as a result of which the switching arm 26 is lifted off the buffer pin 29, however, this means that the stop pin 31 can be displaced in the slot 27. This shift lasts until about 11 p.m., at which time, as can be seen from FIG. 6, the switching arm 26 is in its position

During the entire time, the switching arm 26 is kept unchanged in its blocking position and is then suddenly triggered when the tip of the switching finger Zk comes out of engagement with the nose 25c of the switching arm 26. The process as described above is then repeated.

Referring in particular to FIG 7 will now be referred to the rotation of the weekdays ring ¹ Il are described «* 'The upwardly extending from the switch arm 26 switching pin IJ3 passes through the direction indicated by * arrows motion phases in response to the movement of the switching arm 26.

The absolute amount of this further rotation of the ring l \ l corresponds to the effective length of the slot 27, because it was shown above that the stop pin is close to the end before the switching arm 26 is triggered of the slot

and then near the top of the slot is transferred, as shown in FIGS is. It should be mentioned here again that the switching arm is triggered shortly before midnight.

The phase of movement of the switching arm 26 shown in FIGS. 4 to 6 is initially advised by the switching finger, the switching arm 26 is pivoted about the stop pin 31, while this is simultaneously moved in the slot 27, so that because of the outs - When the cam surface 32 engages with the buffer pin 29, the projection 28 also disengages from the teeth 17 of the data ring 16. During this movement phase, the pin k3 is shifted into the corner Z of its triangular movement phase and then the projection 28 of the switching arm 26 into a next recess is brought between two teeth of the data ring 16, the pin ^ l3 is also brought into a next recess between the teeth of the weekday ring kl .

154813Ί

Although this type is regarded as the preferred embodiment, the pivoting and shifting of the switching arm 26 can also be caused by the fact that the lower section of the switching arm 26 is provided with a slot 26 A which can accommodate one another Base plate fixed guide pin G is used. Csh. Figure 10). As seen in Figure 11, the shift finger is 2 ^l \ in a lying shortly before midnight time again with its front tip in contact with the Nase25c of the switching arm 26, which here is located in the locking position, ie, its cam surface 32 assumes the maximum distance from the bumper pin 29. The guide pin G is then near one end of the guide slot 26 A. If the shift finger 24 is rotated further, its tip then comes out of contact with the nose 25 c, the shift arm is consequently "relieved" or "triggered", d, H.,. under the force of the biasing spring 30, the switching arm 26 is thrown forward so that its cam surface 32 comes into contact with the buffer pin 29.

to limit, but also to prevent it from twisting. The bumper pin 29 thus causes a simultaneous displacement and rotary movement of the switching arm 26,

It should now be pointed out, polyglot advantages the first described embodiment compared to the embodiment according to FIGS. 10 to 12 brings. In the embodiment according to these Figures 10 to 12, the switching arm moves relative to a fixed guide pin, whereby the guide takes place via a slot in the switching arm. In the first The embodiment according to FIGS. 1 to 9 is in the base plate a slot 27 is formed, in which the pin 31 of the switching arm 26 engages so that the Switching arm according to the geometric dimensions of this slot rotate to a limited extent and moved v / ground. By now the guide pin G during the total movement of the switching arm 26 Assumes a constant position, the spring 30 has a considerable Reibungsarbeitpu afford that when triggered of the switching arm results in a reverse according to the work torque given to the spring

It should also be pointed out in this connection that the counter torque increases to the same extent with increasing distance between the tip of the shift finger 2M and the shifter during its pivoting movement, so that provision is made for this in an embodiment according to FIGS It must be grounded that the clockwise torque is sufficiently large to compensate for this undesired overturning torque. However, such clockwise torque also increases the friction between the shift finger and the shift arm when it is triggered, which then also generates energy for the transferring movement of the data ring and the weekday ring is lost. ■

In particular, it can now be seen from FIG are almost aligned in a line in which the pin 31 assumes its lower position in the slot 27. In Figure 8, the switching arm 26 is in its critical position, in which the tip of the switching finger 2'I * ° tends to to jump out of the groove 25 d.

Finally, a third embodiment will be briefly described with reference to FIG. If, according to the second exemplary embodiment, a guide pin G was provided which cooperated with a recess in the switching arm 26, in this exemplary embodiment the switching arm 26 ^{f is provided} with a tongue 26 which is guided between two knob-shaped guide plates M 1 and M ₂ . The cam surfaces of these guide plates are such that the tongue 26'ft can slide back and forth, but can also be pivoted a small amount when the shift finger 2k turns. The advantage of this embodiment, which otherwise works like the other two embodiments, is a lower weight and a simpler structural design, as a result of which obvious advantages are achieved.
